Paul,

I'm almost done with cleaning und inspection of my rotary engine.
Time for me to plan the modifications and the reasembling.

Following modifications are planed so far.
1. Increase the oil flow to the rotors by removing the spring and the
ball from the oil jets in the eccentric shaft and replacing them with
a carburator jet with a 2 mm opening.

2. Disable the eccentric shaft oil bypass valve. Tracy suggests simply
to put a tubular spacer into the recess of the eccentric shaft bolt.
In the overhauling DVD from Bruce Turrentine he removes also the actuating rod.
Is there a difference or are that equal practices?

3. Removing the oil injection pump in order to avoid combustion residue
from the four stroke oil out of the oil pan.
The opening left from the pump drive should be covered with a aluminum
plate. Do you have a picture of such a cover plate and how to fix it
onto the front cover(JB-Weld or bolt on)?

3A. Replacing the Flyweehl with a automatic flexplate mod 86-91 to use
the PSRU from Tracy.
Do I have to rebalance the drive train if I change the flexplate?
I thought every part is balanced on its own, so changing to a different
flexplate doesnt matter.

4. Streamlining the high speed port.
Tracy streamlined the barrel valve from the inlet manifold and
glued it into the high speed port in the full open position.
Bruce Turrentine only streamlined the high speed port without
the barrel valve. I plan to use the lower section of the stock
inlet manifold for designing a new inlet manifold and see no
advantage in gluing the barrel valve into the side housings.
Any recommendations, besides going p-ported ;-)

5. Install the Tension Bolts with some spiral bead of silicone.

Did I forget something or is this a complete To-do-list?

Sorry Paul for pelting you with my lowbrow questions.

Kind regards
Thomas

2? Sounds like equal practice.

3? is a bolt on. Go easy on the RTV you don't want any to get
in the engine. No pictures but it is straight forward.


3A? If you have the proper RX8 counter weight everything should be
in balance. Earlier engines had rotor weight variations so it
was harder to get the right counter weight.

4? Gluing in the barrel valve in an RX8 engine streamlines
it. In previous engines the barrel valve was not streamlined
so JB Weld was used for that purpose. The barrel valve was removed
and should be. Make sure no bits or pieces of the RX8 barrel valve
assembly can vibrate loose and go into the engine. That has happened.

I think that covers it.
